Title: Improvements in magnetic recording apparatus
IPC: G11B20/14
Filed: 1970-03-24
Abstract: 1,243,755. Data storage. INTERNATIONAL BUSINESS MACHINES CORP. 24 March, 1970 [21 April, 1969], No. 14167/70. Heading G4C. In magnetic recording apparatus, bit signals read from a magnetic medium (e.g. tape, disc or drum) through a read transducer are delayed by one bit time and the difference between the delayed signal and a non-delayed signal is obtained. The absolute difference is thresholded to convert the recorded signal (which was frequency-modulated) to pulse/no-pulse form. The thresholder (or later apparatus) is enabled by a clock pulse at each bit-time boundary. The clock rate may vary with the speed of the magnetic medium. The delay is achieved by means of a delay line, or by using a read transducer head having two gaps, one bit cell apart, to provide the delayed and non-delayed signals respectively. The threshold may be fixed or vary with the average signal level of the read signal (or of a plurality of such read signals in a multi-channel system). A sync. signal can be recorded.

Abstract: 262,360. Yorkshire Engine Co., Ltd., Poultney, E. C., Gilling, A. H., and Akroyd, H. A. June 4, 1925. Railway locomotives, steam, of articulated construction.-An articulated locomotive comprises in combination a boiler unit a with driving cylinders d, a tender unit b with driving cylinders i, and valve mechanism for cutting off the supply of steam to all cylinders at a maximum of approximately 50 per cent. The volume of the tender cylinders and the tractive effort exerted thereby are preferably less than the volume and tractive effort of the main cylinders d. The tractive effort of the main cylinders may be arranged to be equal to that provided in a standard locomotive with (say) 90 per cent maximum cut-off, either by making the cylinders d of greater volume, or by use a higher boiler pressure. The exhaust steam from the tender cylinders passes through a feedwater heater and escapes by a pipe o. The water is drawn from the tank h by a pump p and passes through the feed-heater and a valve x either back to the tank or direct to the boiler through a pipe w. The tank may thus be used for thermal storage. An auxiliary supply of steam beyond the 50 per cent cut-off is supplied for starting. This may be effected by means of the piston distributing- valve shown in Fig. 4. Each of the heads 2 of this valve is provided with an auxiliary port or ports 1 adapted to co-operate with a triangular port or ports 3 formed in a bar 5 of the valve liner 4. When the valve reaches the point of cutoff steam can enter the cylinder through the ports 1 and 5, but on further movement of the valve the steam is gradually cut off due to the shape of the port 5.
